2009 Yamaha YZF-R6, YAMAHA YZF-R6 - TRACK READY, STREET SMART The 2009 R6 is designed to do one thing extremely well: get around a race track in minimal time. It?s about a screaming, 15,000-rpm-plus fuel-injected four-cylinder engine in a taut chassis that lets it snap from upright to full lean instantly. Oh yeah: It?s a great street bike too.
